# generates QT makefile for gui
# This monkey stuff is here because i was not able to persuade qmake
# to include our Makefile.flags which contains all configuration stuff
# Therefore we are building in two stages:
# * gui/Makefile.gui simply generates gui/Makefile from gui/pdfedit.pro
#   and includes this file to the gui/Makefile.gui
# * gui/Makefile.qt is in full power of qmake and we simply refers to our
#   configuration variables. These are not visible to the Makefile 
#   directly, but we never use gui/Makefile.qt directly but rather as
#   included in gui/Makefile.gui
# Seems to be complicated and if someone finds better solution how to
# get include ../../Makefile.flags into the generated makefile then
# it can be safely removed.
# We need to generate online help (unless it is generated yet) before
# QT makefile is created (because of file expansion used in project
# file)
# For the same reason we have to generate localization files too
